If it was flooded with gas in the first place, then the problem is not fuel. You need to check that individual spark plug for spark, and replace all four while you're at it.

Get 4 new plugs, pull the wire off of cylinder four and place it on one of the new plugs before you change anything. Have someone try to start it and watch to make sure it sparks. Make sure you still have the old plug in the hole when you crank it or you'll have a terrible mess. If it hasn't been done in a while, go ahead and replace your wires.

What about the injector seal, sounds like it might be leaking.

NM, I'm losing my mind. Maybe there's some interference in the wiring and it's just dumping fuel.

Dude, definitely change your oil, like now. You were dumping so much fuel in there, its mixed with your oil, destroying its lubricating capabilities.
